TABLE-LEV E LER.

To all whom it may concern."

Be it known that I, ALEXANDER KovAos, a subject of the King of Hungary,and resident of Sharo11, .in the countyof Mercer and State ofPennsylvania, have invented certain new and useful Improvements inTable-Levelers, of, which the following is a specification.

,The present invention relates to improve-' ments in devices forleveling tables and the like, and has for its object to provide asimple, inexpensive device of this character,-

which may be easily applied to the table on which it is desired to beused.

Many devices have been heretofore used,

usually comprising screw bolts and nuts.

()ne of these elements is usually fixedly/use;

while the :bth'er is rotamay be rotated by means cured to the table,tably arranged and of a suitable tool, such as an operating lever;

It is obvious that when such a table stands in the corner of 'a room, oron some other place where notmuch space is left for turning acomparativel it will be very dilhcult to adjust the level of the table,and in many instances it will be necessary to remove the table in orderto have space for operation.

The present invention now provides a, table levellng device which doesaway with the rotatable screw elements and does not need, therefore, anoperating lever, but comprises a rack and pinion adjustment, the pinionof which may be operated by a socket wrench, not needing much space for.operation. a

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a portion of a table, having its legequipped with the leveling device, embodying the invention. Fig. 2 is avertical section of part of the leg and the device, and Fig. 3 is ahorizontal section on line 3,3 of Fig. 2.

In the drawings, 1 indicates a billiard table, the drawings, and 2denotes one ofthe legs of the usual construction, attached to the tablein any suitable manner.

To the lower end of the leg 2 is attached the leveling ,device 3. Thisleveling device comprises a base 4, resting on a plurality of balls 5,arranged thereon in any suitable manner known in the art. In thisparticular case holding plate 6 is provided, secured to the base bymeans ofscrews 7. 7. To the p I Specification of Letters Patent.Application filed May'2, 908.

use 4 are attached, or preferably made integral with the same, a rack 8and a guide-rod preferably of qpadrangular cross section. Both the rackS and the guide-rod 9 project fromtbe upper face 10 of the base 4 andare arranged parallel to the axis of the table leg A block 11, similarto the base 4, is at tached to the table leg 2, preferably by means of ascrew 12, and has arranged thereon a rack 13 and a guide-nod 14, in thethe rack and guide-rod of the base.

It is obvious that the rack and guide-rod of the block 11 must belocated in, planes not coinciding with the planes of the rack andguide-rod of the base 4, so as not .to interfere with the same. a

A substantially cylindrical member '15 is provided and arranged thereonas adownwardly extending flange 16, fitting the upper portion of thebase 4, which portion is reduced in diameter, and an upwardlyextendingflange 17 fitting the lower portion of the block 11, which portion isalso reduced in diameter. Through the Whole length of this cylindrialmember extend rectangular holes 18, 18, adapted to receive the racks andguide rods", hereinbefore described.v The cylindrical member 15 isfurthermore provided withi'a recess 19, arranged at right angles to theaxis of the same, in which recess is located a pinion 20, fixedlysecured to a shaft 21, the latter being journaled in the cylindricalmember at 22, and. in a plate 23, secured to the cylindrical member. Thepinion 2O meshes with the racks-8 and 13, and may be rotated by means ofa' wrench engages the square head 26 of the shaft 21.

Inorder to prevent the backward rotation of the pinion 20,,the shaft ofthe same is provided, preferably on its outer end. with a ratchet 27, inoperative engagement with a pawl 28, pivoted to the plate 23.

The operation of this device is obvious. lVhen it is desired to raisethe level of the table, the wrench 24 is brought into engagement withthe square head 26, and the pinion turned. whereby one of the racks,that is rack 13. will be-raise'd and the other of the racks, that israckS, will be lowered. The ratchet and pawl arrangement prevents thebackward movement of the pinion and thus the downward and upwardmovement of the racks, keeping thereby the level of the table in apredetermined height. Shoul it be sired to lower the level of the table,then, first, the pawl is disengaged with the ratchet,

-- second, the pinion rotated until thedesired level'is obtainedand,finally,the pawl brought again into. engagement with theratchet. It

will be, observed that the base, which rests on the floor. or carpetdees'not rotate, and thus does not injure the same. After the desiredlevel is attained, the Wrench may be taken off, so as not to impair theappearance of the table.

It isobvlous that the square head does not necessarily project from thecylindrical membeij', but may be located within the same together withthe ratchet and pawl.
